东秦岭汤河—二郎坪—刘山崖—马畈蛇绿岩套

河南东秦岭分布着四个时代不同的蛇绿岩带,由北向南依次为:1.碾道沟—马市坪蛇绿岩带; 2.汤河—二郎坪—刘山崖—马畈蛇绿岩带;3.洋淇沟—柳树庄—卧虎蛇绿岩带;4.淅川—桐柏—商城蛇绿岩带(图1)。不同岩带的蛇绿岩,尽管规模不等,出露完整程度不一,但均分布在分割不同构造单元的深断裂带附近,且常伴有高压低温变质或混杂堆积带。

ANALYSIS ON AGRICULTRUAL INFORMATION DEMAND——Case of Jilin Province

With the rapid development of agricultural informalization in the world, the demand of agricultural information has been a focus in the international agriculture and information fields. Based on the investigation, this paper presented the four characteristics of the demand of agricultural information in China, includingregionality, seasonality, great potential demand and variation in kind and level. The factors infuencing the demand of agricultural information were analyzed by the Optimized Less Square （OLS） method. The result shows that, of all factors influcing agricultural information demand, the most important one is economy, the second is facility of information pass, and knowledge and education of user, credit of agricultural information service system and production situation follow. Taking Jilin Province as an example, this article also elaborated the agricultural information demand status, and deduced the regression model of agricultural information demand and verified it by the survey in rural Jilin.     

TSENGIELLA, A NEW GENUS OF DELESSERIACEAE——(RHODOPHYTA) FROM CHINA

A medium-sized delesseriaceous red alga has been collected from the subtidal area of the northern Huanghai Sea coast. The characteristics of the specimens precludes their being placed in any genus defined by the currently accepted criteria. Tsengiella gen. nov., with T. spinosa sp. nov., as the type and only known species, is created and allied with the Hypoglossum group of-the Delesserioideae (Delesseriaceae, Ceramiales, Rhodophyta).     

Structural feature and tectonic evolution of Awati——Bachu area in Tarim Basin

The research area is situated in the western part of Tarim basin, which includes Awati depression and Bachu uplifted block. It underwent three times processes of compression in a large scale and a near term extension since Cambrian. The first compression occurred during Middle Cambrian to Devonian, which formed fault band folds in NW axial direction. They were ＂under-water uplift＂ and distributed all over the research area. The second compression occurred in Late Permian and formed fault band folds and a few fault propagation folds in NS axial direction. They are developed near Tumuxiuke fault belt and the northern research area. The western anticline is bigger than the eastern one in extent and size. The third compression occurred during Palaeogene to Quaternary and formed tumuxiuke fault belt and fault propagation folds in NW direction. They are distributed over the south part of the research area. Tumuxiuke fault belt is a big scale dextral reversed strike-slip fault belt; it transformed or destroyed the fold structure of the research area. A short-term extension occurred during Early Permian. Tarim Basin is in the rift forming stage of craton, and there exist widespread basic vol- canic rocks, basic intrusive bodies and dikes.     

RELATION BETWEEN THE MRT BUILDING AND UNDERGROUND SPACE EXPLOITATION ——A Case in Guangzhou City

Research on natural resources and environmental geology for urban sustainable development: a case study of Kunming

There exists synchronous growth in resources consumption and environment pollution in Kunming urbanization in recent years, which has led to the increasing pressure of urban sustainable development. Considering the environmental and social benefits in Kunming’s water resources sustainable development, the authors provided a research finding the optimal urban population scale in different stages for urban water supply based on the sustainable development groundwater evaluating theoretical model. Through the research on the availability of construction site as well as the risk in underground space exploitation with the extenics theory method, we get a suitable partition map of land for urban construction and a risky partition map of underground space development. The results show that the appropriate population scale of Kunming will be less than 2.96×106 by 2020, and will reach (4.34--2.96)×106 optimized population scale after 2020 under the condition of economic-socially and environmentally sustainable development. It is significant to optimize urban construction land and use underground space under the condition of land resources sustainability in Kunming.

城市地铁站点商业价值数字化评价方法

地铁站点商业价值是地铁改变城市交通方式基础上城市商业业态价值的体现,对其科学和量化的评价是地铁站点建设重要的方面。本文首先对地铁站点商业价值的评价从商业等级与商业规模两个方面进行了体系构建,然后以广州地铁八号线为研究对象基于此体系进行了商业价值的评估。在地铁站点商业等级评价中,选取5个空间因子与2个非空间因子进行多因子评价。在进行空间因子评价中的商圈因子分析时,基于市级和区级商圈周边商业用地基准地价具有一致性的距离衰减特征,创新性的构建了商业地价的空间衰减函数,并据此将这一衰减函数转换为商圈距离衰减因子评价值的函数与量化定义,有效解决专家赋值存在的主观性问题。以此方法对八号线地铁站点商业等级进行评价,在完成空间因子评价以及非空间因子校核后,发现上下九-文化公园区域的商业等级最高,次一级则分布在荔湾区中部。对于商业规模的评价,则以商业建筑面积需求平衡方法,基于地铁站点服务半径内人口规模的评估以预测潜在的商业人口数量,并据此估算未来的商业建筑面积需求。以此方法,对地铁八号线以陈家祠站为例对该站点进行了商业建筑面积需求的预测。本研究提出了基于地价距离衰减与量化评价的因子评价方法完善的相关的方法体系,以数字化模型构建商业等级与商业规模的量化评价提高了地铁站点商业价值评估方法的合理性和科学性。
